Tmobile G2. Started losing network every so often. Would need to reboot or sometimes switching to airplane mode and back would work. Then it just wouldnt work at all. Went to Tmobile store and they gave me a new SIM card. Tried that, and still no luck. SIM works fine in other phones.
I tried multiple cards, and they seem to work fine so long as I apply heavy pressure to (push down on) the card while using the phone. If I let go, the network drops within seconds. Must be the SIM slot itself..
Anyone ever replace the slot on a G2? I think it's soldered directly to the board, but I havent taken it apart yet. Hopefully it's just a few points that I can easily remove. Where can I get a replacement though? Anyone know parts that have matching solder poins?
yeah its soldered to the motherboard and unless you are amazing at soldering it will be tough, to top it off I've never seen one on ebay or amazon so you'll have to dig for one

I've been looking for the part too, had some luck just resoldering the old one, twice(!).
CAREFUL if you do this. AND DON'T push on the sim slot. This will wreck/crack the traces for the solder for the SIM holder itself. The holder is soldered to the surface of the MoBo. Mine (mobo) got damged on the second solder operation, some traces came off of the board. There is a place I found that will repair it for you for 89bux, but seems pricey to me.

looks like compatible sim holder

I'm going to order it (only 1 buk) and give it a whirl. Will post results.
what was the result?
I have a tendency to hop back and forth between phones. Today I went to put my sim card in my Note 2. I use a nano sim card adaptor (I decided to experiment with the iPhone 5 for about a month...) to put my sim card in my Note 2 and my Nexus 4. Unfortunately, the sim card fell out while I was putting it in my Note 2 today and the adaptor got stuck in the tray. After a few moments of agonizing struggle, I got the adapter out. Now my Note 2 won't recognize my sim card. I think the prongs at the entrance of the slot were damaged, since that's where the adaptor kept getting hung up.
Is there a way to find out if it's completely broken or if the prongs are just out of place? And if it's broken, does anyone know how much a repair would cost? I don't know that I have the confidence to try to repair it myself.
Thanks.

The SIM card reader module I'm fairly certain is soldered onto the logic board, so unless your good with soldering, a replacement SIM reader isnt very practical. However, the Sprint Epic Touch (GS2) sd card reader module is attached only by a simple flex cable, so its possible the same may apply here. If this were the case, the replacement part shouldnt cost more than 10-20$ (assuming their available) and replacement would be as hard as taking the back housing off.
Try comparing the SIM slot with another similar model and see if you can see if something is out of place. See see see see see see.:good:
I think I may have done the same to mine with one of those SIM adapters. I've ordered this and it should be here in a few days. I'll give it a go...

u did the same exact thing i did lol but what i thought was a damaged sim tray was somehow just corruted firmware when i restored back to stock everything worked just fine i even called samsung and they were going to replace it but since i live in Hawaii i didnt want to wait so i just did a restore in odin and everything works fine
if u are really damaged ur stim tray and dont wanna wait on samsung u can try this

but good luck try restoring with odin first
I'm glad I'm not the only one to have had this problem, heh heh.
Anyway, after watching the video, I think I'm going to send my Note to Samsung and have them fix it. I would probably ruin my phone if I did it myself. Should I do a factory reset to protect my data before doing so? I don't know if they'll be sending the same phone back to me, since it says they may replace it with another if they determine that they aren't going to fix the part that's broken.

they will wipe ur data if ur rooted and have a custom rom on your phone u need to return to stock and set the flash counter to zero.
u would send the phone is no battery no battery cover no sim card so sd card just the phone nothing else
try to restore ur phone via odin first
http://galaxynote2root.com/galaxy-n...ootunbrick-galaxy-note-2-with-stock-firmware/
if u still get no sim card error after doing that then give samsung a call phone number is on the phone itself under battery and they will send u a box and u should have to wait about 2 weeks then u will either get a fixed phones or a replacement not sure how they do it since i fixed my no sim issue with odin
I did the same thing once. Just called att and told them it wasn't reading a simple anymore and they sent me a new one.

My Fix For Broken SIM Reader Pin
This is an old thread, I know. But the problem is ongoing. These SIM card adapters are just plain evil. Now that this has happened to me, I googled the issue and see that there are tons of folks suffering. I am posting this reply so that others can see the "fix" I managed for my International Samsung Note I. I am sure it can be applied to most other phones.
I should point out that in order to get any usable access to and visibility of the SIM card reader I had to remove the battery cover and the back from the phone's touchscreen. This reveals the motherboard to which the SIM card reader is soldered. I found a good video on this at YouTube. It wasn't that hard although I did not have the plastic pry bar they used - I think I will get one for the future. I managed with a small flat head jewelers screw driver and an ancient, plastic shirt collar stay. (I can hear my mother saying "save it - you'll find a use for it!" I hate it when she is right.) Once complete I could move on.
At first, I tried to replace the SIM card reader pin that was broken off by the SIM card adapter with a tiny piece or rolled-up tin foil. I saw someone else reference this approach and it seemed possible and cheap. Alas, it did not work. After many attempts, the phone simply would not recognize any SIM card. I finally got to sleep at 3am.
I then found a piece of brass shim stock that I have had lying around for years. (I am hearing mom again!) It is item 1412110231, Brass Strip .016x1/2inx12in shown here. I got mine at the local hardware store for some other aborted project. I used some snips to cut off a tiny strip from one end and then cut that strip to maybe 1/3 to 1/2 its overall length. The idea was to place the strip inside the SIM reader slot where the pin had broken off in an effort to create a contact point to replace the pin. Cutting the tiny strip off the stock piece caused the tiny strip to bow a bit. It turns out that was a good thing but I had to reduce the amount of bow quite a bit for it to fit inside the reader. Remove any rough edges from the tiny strip with a file.
With the touchscreen assembly lying flat on the table I managed to get the tiny strip in place. I was then able to slowly and carefully slide the SIM card into the reader and this resulted in a contact good enough to make the phone again recognize the SIM card and for cell service to be restored. Hurray! Yes, I was able to carefully place the battery in its bay and operate the power button to perform testing.
But you must remain aware that the tiny strip is just lying in the slot and is held in place only by friction/pressure from the SIM card inserted into the reader. Therefore, for the rest of the phone's life, it requires great care when removing the SIM and handling the phone when a SIM is not installed . Basically when removing the SIM, the phone MUST remain flat on its display until the SIM is re-installed. Moving the phone around in other orientations without a SIM card installed will definitely cause the tiny strip fall out. And who knows what hell that will cause?
You cannot put the phone's back onto the touchscreen with the SIM card in place. At first I thought about cutting the SIM's length down so the back would install even with the SIM in place. Before doing this I tried to carefully snap the top portion of the back onto the touchscreen while it all remained flat on the table so the tiny strip wouldn't move. With the top 1/3 of the back snapped on, I could just manage to insert the SIM through the phone's cover and have the tiny strip held in place by the SIM while I snapped the rest of the back into position. This worked pretty well but your mileage may vary.
I basically plan to leave the SIM in place forever - even if it is not to be used. I also put a reminder note on the battery so that I am less likely to forget that I made this hack.
I hope the annotated photos help those who follow me - as surely others will do. Good luck. I was very lucky to have destroyed only one pin and for it to be in the most accessible part of the SIM reader.
Hi,
recently i was in New Orleans (quite hot and sticky, very humid) and was changing the battery on the phone, soon as i did this the Sim Card wouldnt be recognised, which i found abit odd and with numerous attempts at removing the sim card to no avail, soon looked behind the battery to discover the water damage mark was set to red and crosses, assuming it was water damaged somehow i took it to a shop who replaced the sim card tray and checked the phone for water damage... there was none which is alot more striking, had this confirmed with about 5 other phone repair shops that there isnt water damage despite the indicator telling me there is and the sim card tray replaced about 3 times now.
Is this a common problem? what could it be? i'm now left with a overely expensive brick of a tablet.
I bought my brother a second-hand M8. It had a cracked screen but it was really cheap. I put the new screen in and a new SIM card reader. Everything worked fine for months and out of the blue the screen stopped responding to touch. Everything else worked fine as far as I could tell. Even in TWRP touch was gone so I figured maybe it was a cheap screen or something like that. I took it apart and the backlight was falling apart. Ordered a new screen that had the frame with it to save time on reassembly and because the old one was a little tweaked. Same problem, ran the RUU from Windows, ran different RUU's from several threads via Fastboot. Ran the latest firmware package on Santods thread and still nothing. It has to be the motherboard at this point right? The display and digitizer cables go right into the motherboard and the only cable that looks replaceable goes up int the daughter board with the cameras and top speaker assembly. Am I missing something or should I just scrap this mess?
4/5/16: I have since purchased a used motherboard from eBay. This has corrected the issue with the digitizer not working. The SIM card will not be recognized now is the problem I am fighting with. It was giving me this issue before on the old phone but it was off and on. I got it to work once with the new motherboard installed. I have RUU's and everything. This motherboard is S-ON and I don;t want to waste another $25 on Sunshine if the problem isn't software related. I have also replaced the daughterboard and the flex cable as well as used a different SIM Card reader. I am out of ideas at this point.
Does anyone know if there is a way to make sure a motherboard from eBay will work?
No one has any idea?
In my case, as I took my M8 apart because of cracked screen and as I put it back together my M8 couldn't recognize my Sim and what helped in my case was that I've put a piece of thicker tape on my Sim just so it is thicker than it was and since then everything works flawlessly.
Hope this helps you,
Regards Talpes
Hi all,
I recently traveled overseas and purchased a second SIM card for data and the shop assistant probably broke the tray while inserting the card. Fast forward to today, I'm stuck with a broken SIM tray that allows me to only change SIM-2 as SIM-1 is stuck in the broken tray that is still inside the phone. I've went down to the service center and found out that it costs $40-50 for repairs because they have to take apart the entire phone. I think this is a little unreasonable and I'd like to know if there is any way to remove it myself and replace it with a $4 tray bought from ebay.
Thanks!
